Among them, architectural glass is often used for isolating wind and transmitting light, and is often made into a sheet shape. The edge of the glass manufactured into the sheet shape is sharp after being cut, and potential safety hazards are easily generated, so that edging treatment is needed to be carried out on the edge of the glass. In the edging process, in order to ensure that the grinding tool can uniformly and accurately grind the edge of the glass, a plurality of fixing mechanisms or positioning mechanisms are needed to fix the position of the glass. The positioning device commonly used at present is basically provided with a plurality of suckers at the bottom of glass to be edging, and then the suckers are sucked tightly to fix the glass. And the sucking disc is often placed along glass edge when arranging to avoid glass limit portion unsettled and shake when leading to glass edging, influence edging precision and edging quality. However, in such a positioning manner, the specific placement position of the suction cup is often determined by means of human experience, and after the glass is placed on the suction cup, the position of the suction cup is often required to be adjusted repeatedly, so that the suction cup corresponds to the glass well, more time is required to be consumed in the process, and for large glass, the adjustment is very inconvenient, so that the overall positioning efficiency is low; moreover, the distribution of the suction cups which are simply and manually adjusted is disordered, the distribution of the suction force is disordered, and the suction effect is poor. And the arrangement mode placed along the glass edge is that for large glass, a large amount of suspension exists in the middle of the large glass, the middle is not supported, and when the glass edge is stressed in edging, the force can squeeze the middle of the glass, so that the glass is easy to damage, and the glass quality is affected.
